Merge tag 'soc-drivers-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC driver updates from Arnd Bergmann: "As usual, there are lots of minor driver changes across SoC platforms from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung. These usually add support for additional chip variations in existing drivers, but also add features or bugfixes. The SCMI firmware subsystem gains a unified raw userspace interface through debugfs, which can be used for validation purposes. Newly added drivers include: - New power management drivers for StarFive JH7110, Allwinner D1 and Renesas RZ/V2M - A driver for Qualcomm battery and power supply status - A SoC device driver for identifying Nuvoton WPCM450 chips - A regulator coupler driver for Mediatek MT81xxv" * tag 'soc-drivers-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (165 commits) power: supply: Introduce Qualcomm PMIC GLINK power supply soc: apple: rtkit: Do not copy the reg state structure to the stack soc: sunxi: SUN20I_PPU should depend on PM memory: renesas-rpc-if: Remove redundant division of dummy soc: qcom: socinfo: Add IDs for IPQ5332 and its variant dt-bindings: arm: qcom,ids: Add IDs for IPQ5332 and its variant dt-bindings: power: qcom,rpmpd: add RPMH_REGULATOR_LEVEL_LOW_SVS_L1 firmware: qcom_scm: Move qcom_scm.h to include/linux/firmware/qcom/ MAINTAINERS: Update qcom CPR maintainer entry dt-bindings: firmware: document Qualcomm SM8550 SCM dt-bindings: firmware: qcom,scm: add qcom,scm-sa8775p compatible soc: qcom: socinfo: Add Soc IDs for IPQ8064 and variants dt-bindings: arm: qcom,ids: Add Soc IDs for IPQ8064 and variants soc: qcom: socinfo: Add support for new field in revision 17 soc: qcom: smd-rpm: Add IPQ9574 compatible soc: qcom: pmic_glink: remove redundant calculation of svid soc: qcom: stats: Populate all subsystem debugfs files dt-bindings: soc: qcom,rpmh-rsc: Update to allow for generic nodes soc: qcom: pmic_glink: add CONFIG_NET/CONFIG_OF dependencies soc: qcom: pmic_glink: Introduce altmode support ...
